Define the job first

• →What business event should start the integration?
• →Which system owns the customer, order and financial record?
• →Which fields need to move, and in which direction?
• →What is the expected result and who investigates a failure?

Prepare a mapping sheet

• →Source record identifier → destination record identifier.
• →Customer and organization association.
• →Vehicle identifiers and transport requirements.
• →Full addresses, contacts and date/time zone handling.
• →Currency, amounts and business status meanings.

Keep identifiers stable. Display names are useful to people but are poor keys for linking records.

Request the supported contract

• →Authentication method and organization scope.
• →Available endpoints, operations and required fields.
• →Pagination, filtering and limits.
• →Validation errors and permission errors.
• →Duplicate prevention or idempotency behavior.
• →Versioning, sandbox access and change-notification process.

Plan for ambiguous outcomes

1. 1Keep a correlation reference for each logical operation.
2. 2When a request times out, check whether the destination already created the record.
3. 3Retry only using the supported duplicate-prevention mechanism.
4. 4Record the outcome without logging credentials or unnecessary personal data.
5. 5Give an operator a way to resolve failures that cannot be retried safely.

Before production use

• →Test successful creation, rejected input, missing permission and interrupted requests.
• →Verify the resulting record in the destination system.
• →Confirm monitoring and who owns recovery.
• →Agree on a controlled rollout and a way to stop new writes.
